Bipolar ionization (BPI) is an active air purification technology that releases positively and negatively charged oxygen ions into an indoor space.
These ions bond with airborne contaminants—including pathogens, fine particulate matter (PM2.5), volatile organic compounds (VOCs), and mold spores—causing them to cluster together (agglomerate) so they are easily captured by HVAC filtration or neutralized on a cellular level.
See how plasma air purification and soft bipolar ionization technology work together to clean indoor air of harmful pollutants.
Ions Cluster Airborne Particles
Charged ions bind to ultra-fine particles, grouping them into larger, easier-to-trap clusters.
